Reversible Superdense Ordering of Tetragonal Lithium in a Layered Material
Natalie L. Williams, Stephen D. Funni, Sihun Lee +14
Understanding lithium (Li) ordering and dynamics is foundational in energy storage. X-ray based experimental methods do not simultaneously provide atomic structure information toge…
Directionally Locked Heteroepitaxy with a Structurally Modulated van der Waals Material
Nitish Mathur, Guangming Cheng, Francesc Ballester +17
Precise orientation of symmetry-mismatched epilayers on van der Waals (vdW) substrates via heteroepitaxy has commonly been achieved through surface treatment processes to accommoda…
Clustering-Enhanced Time- and Angle-Resolved Photoemission Study of LaTe: Absence of a Photoinduced Secondary CDW in the Electronic Structure
Gesa-R. Siemann, Davide Curcio, Anders S. Mortensen +9
Optical control offers a compelling route for tailoring material properties on an ultrafast time scale. Ordered states such as charge density waves (CDWs) can be transiently melted…
Large Thermopower with Sign-Alternating Quantum Oscillations in Insulating Monolayer WTe2
Yue Tang, Tiancheng Song, Haosen Guan +13
The detection of Landau-level-like energy structures near the chemical potential of an insulator is essential to the search for a class of correlated electronic matter hosting char…
Unconventional Superconducting Phase Diagram of Monolayer WTe2
Tiancheng Song, Yanyu Jia, Guo Yu +13
The existence of a quantum critical point (QCP) and fluctuations around it are believed to be important for understanding the phase diagram in unconventional superconductors such a…
Uncovering the Hidden Ferroaxial Density Wave as the Origin of the Axial Higgs Mode in RTe
Birender Singh, Grant McNamara, Kyung-Mo Kim +24
The recent discovery of an axial amplitude (Higgs) mode in the long-studied charge density wave (CDW) systems GdTe and LaTe suggests a heretofore unidentified hidden order.…
